Question

Quizplus · Accepted Answer

External respiration refers to the exchange of gases between the lungs and the blood, specifically the exchange of oxygen and carbon dioxide in the lung.

Answer: B
 Internal respiration refers to the exchange of gases between the blood and the body's tissues, specifically the exchange of oxygen and carbon dioxide in the tissues.

Answer: C
 The diaphragm is the primary muscle responsible for breathing, contracting to inhale and relaxing to exhale.

Answer: D
 The abdominal muscles also play a role in breathing, contracting to help force air out of the lungs during exhalation.

Answer: E
 Oxyhemoglobin is the form of hemoglobin that is bound to oxygen, allowing for its transport from the lungs to the body's tissues.

Answer: F
 Bicarbonate ion is an important molecule involved in the transportation of carbon dioxide from the body's tissues to the lungs for elimination.

Answer: G
 Tidal volume refers to the amount of air that is moved in and out of the lungs during normal breathing.

Answer: H
 Vital capacity is the maximum amount of air that a person can inhale and exhale during a forced respiratory maneuver.

Answer: I
 Aortic bodies are chemoreceptors located near the aorta that help to regulate blood pressure and respiratory rate.

Answer: J
 Stretch receptors in the lungs help to regulate breathing by detecting changes in lung volume and transmitting this information to the brainstem.

Answer: K
 Pulmonary ventilation refers to the process of moving air in and out of the lungs, which is necessary for gas exchange to occur.

Answer: L
 Dyspnea refers to difficult or labored breathing, which can be a symptom of various respiratory disorders.

Answer: M
 Residual volume refers to the amount of air that remains in the lungs after maximal exhalation, which helps to prevent lung collapse.

Answer: N
 Eupnea refers to normal, unlabored breathing, which is necessary for gas exchange to occur in the lungs.
